Once that was accomplished, the auburn-haired Heidi caught up with her fast-walking partner.

Jillian brought her adopted daughter Lukensia home from Haiti less than a week after Heidi gave birth to their son Phoenix in May.

The tough-talking trainer 'came out' in the January 2010 issue of Ladies Home Journal and made no apologies for her lifestyle.

'Let’s just say I believe in healthy love,' Jillian told the magazine.

'If I fall in love with a woman, that’s awesome. If I fall in love with a man, that’s awesome. As long as you fall in love... it’s like organic food. I only eat healthy food, and I only want healthy love.'

It's been a year of change for Jillian, who recently confided that her new role as a mother is one of the most 'magical, meaningful and rewarding' of her lifetime and also one of the most 'chaotic' experiences.

Jillian, who took some time off to concentrate on her newly expanded family, now makes it a priority to include them in her exercise regime.

'Get comfortable with being uncomfortable' is one of Jillian's most repeated and inspiring quotes on the NBC show.

'I like to take Phoenix hiking in a Björn, or Lu for a bike ride in the sidecar or out with me on the paddle board,' she told People.com.

'I take them for jogs with my jogging stroller, and we love to play on the beach. I do everything I can to be active with my kids.'

Now the fitness guru has returned to the 14th season of The Biggest Loser, which premiered on January 6, to kick those competing contestants into shape and hopefully a better and more healthy life.
